FIBAE3 sounds quite interesting. Do they respond well to EQ-ing?

The F3 is very interesting, as are all of the FIBAE models. I am not an EQ user but I am pondering what frequencies someone would want lift on with the F3.

I don't wrote about impedance, only output power and cable no change signature a day to night,

Guys let's don't misinform people here the signature of FIBAE IEMs won't change much on the sound source - the effects of sound sources are measurable. There might be small differences between source that have very very low and very very high impedance but nothing that would make a night and day difference like with old designs which can result in >5dB output differences. If you take the sources with output impedance that are close to each other the difference should be negligible.
Finally please note that because FIBAE IEMs have relatively low impedance they might not be suitable for some amplifiers designed for high impedance load - like tube amps - in that case the distortions would increase affecting the IEMs performance.
Cables - as proved pages ago do make a difference due to noticeable changes in cross-talk. It has been measured and confirmed.

I don't wrote about impedance in source, only for output power in source, in more power FIBAE3 have more treble. Change cables different very signature on Forza Claire Hybrid FIBAE3 is very dark, no brightness, no sparkle treble, on EA Eros II I have sparkle treble, forward vocals, very controlled bass, on stock cable FIBAE3 are flat. On DAP Cayin N5 II FIBAE3 are very dark, bass "bloated", on Fiio X7 dark, smooth, on AK1000SS very flat and analytics, on Shozy Alien+ are brightness, sparkle, with extended punch.


I now use EQ in Neutron Player Meizu Pro5, I have a little add 0,30dB to 3kHz, and 0.4 to 7kHz, because this smartphone not enough power to drive properly F3.

I would like to know calculations to support this theory

On DAP Cayin N5 II FIBAE3 are very dark, bass "bloated", on Fiio X7 dark, smooth, on AK1000SS very flat and analytics, on Shozy Alien+ are brightness, sparkle, with extended punch.

Plausible explanation is that each player has native EQ coded inside the software, which might be the case especially for Andro-based players - I remember some time ago there were revisions of software for example for X5 and some iBasso DAPs that changed how the player sounded. FIBAE won't work against actual EQ - which is fairly obvious.

For first quote. In higher power output than more treble, FIBAE3 get more sparkly. Check this on DAP/AMP with power output above 200mW and change gain. If player or amplifier have 5-50mW treble not expressive, not clear, a low presence.

For secondary quote I agree. In FIBAE3 everything depends of source and cable.

What is your experience with Fibae3 hiss? I'm using it with iBasso DX200 AMP 4 and Cowon Plenue R (both SE and balanced out) and original or aftermarket Forza Audio cables and my Fibae3 hisses quite a lot. This is slowly starting to drive me crazy as Piotr told me they never had any hiss issues reports...

I haven't heard any hiss with FIBAE 3 but have only used it with AR-M20 so far. I've heard hiss with the AMP 4 is common but can't verify that as I don't have it.

Never heard anything about AMP4 hiss (I know DX200 thread quite well). Anyway, the hiss is almost at the same level with AMP1 and 3 and even on Plenue R which is supposed to be very quiet... My Harmony 8.2 is almost dead silent on these two DAPs. I wonder where is the problem...

Time to admit that you have tinnitus? (I'm kidding!)

I only have Amp1 and Amp3, but I have never had issues with hiss and the F3... it could be a faulty amp module?

I have the F3 paired with the AMP4s, and no hiss whatsoever. AMP 1 is fine as well

Hi @piotrus-g, I'm a bit new here, but could I ask if there are any limitations to what you and your team can pull off with regards to CIEM design? I'm quite likely to pick up a FIBAE 2 for my next IEM, and after seeing some of the stuff CA has done, I've come up with quite an interesting design (or so it feels to me).

Good question, man. I've often contemplated getting custom shells forged of walrus semen. Curious what the Polish sentiment is on that.

uhhhh...I don't think that would be kind to the whales though. What did they ever do to you?

 

[PinkyPowers]

There's plenty for everyone.

Send us email with your design specs and we will let you know. If you are looking for extra customization just keep in mind that acrylic offers more than silicone.

No experience in that department, walrus is not a species native to Poland.
